Inner flock coating for vehicles with indicative and/or decorative motif and its manufacturing process

ABSTRACT

This invention relates to an inner flock coating for vehicles with an indicative and/or decorative motif and the manufacturing process thereof, which inner coating is made up of a support, an adhesive layer and a flock layer made up of a set of fibres adhered to the support via the adhesive layer, wherein said motif is located on a visible surface of said inner coating and wherein said motif is performed by the combination of at least two visibly different areas of the coating, a first area and a second area on which a laser beam is applied.

OBJECT OF THE INVENTION

The present invention relates to an inner flock coating for vehicleswith an indicative and/or decorative motif of the ones made up of atleast one flock layer formed by projecting a series of fibres over asupport by flocking, such that said fibres remain adhered to saidsupport via an adhesive layer placed over it.

The invention is characterised by performing said indicative and/ordecorative motif on said inner coating by the action of a laser lightbeam on the fibres forming the flock layer, such that it eliminates partof the flock layer due to a temperature increase when aiming a laserlight beam on said flock layer, revealing the adhesive layer.

BACKGROUND OF THE INVENTION

Flocking is a special technology intended to coat a surfacedecoratively. This technology allows applying fibres by fixing them to asupport material that has previously been coated with an adhesive. To dothis, an adhesive is applied on a support, over which adhesive layershort fibres called flock are projected in order to form a flock layer.

The use of flock coatings is known for application in inner vehicleparts, particularly in automotive vehicles, such as sunshades, pillars,roof, door and seat trimmings, for example. One example is German patentdocument DE 3622263.

These coatings can be applied mainly in two ways, by flocking a supportthe configuration of which has two dominant dimensions for itssubsequent application on a formed workpiece, called two-dimensionalflocking, or by its direct application upon the surface of athree-dimensional workpiece, called three-dimensional flocking.

In the first case, we start from a two-dimensional laminated support, atextile support for example, to which an adhesive layer is applied.Subsequently, by means of an electrostatic flocking process consistingin projecting the fibres forming the flock layer onto an adhesive layerthrough an electrostatic field so as to make them all face the samedirection, for example, these fibres are distributed with an orientationthat is perpendicular to the support.

Finally, the adhesive is subjected to a drying process and the flocksurface is cleaned in order to eliminate any fibres that are notproperly adhered to the adhesive. Once the flock support is obtained, atextile support, for example, it is used to coat a formed workpiece or aworkpiece is formed at the same time in order to obtain a finalworkpiece.

Another way to apply the flock is by applying the adhesive layerdirectly on the three-dimensional workpiece in order to subsequentlyproject the fibres on said layer, which is called three-dimensionalflocking. In this case, the support is the formed workpiece itself.

The application of indicative and/or decorative motifs on this type offlock coatings can be achieved for example by modifying the colour ofthe fibres applied by dying them prior to their application.

Another way of applying motifs can be by the use of fibres withdifferent geometric characteristics, or the localised application ofsuch fibres on the support, copying the design of the motif to berepresented on the support.

Another technique that is known in order to apply motifs on flockcoatings consists in engraving the motifs by the action of a laser beamthat melts part of the fibres forming the flock, producing differenttones between the area on which laser beam has acted and where it hasnot.

In this case, the effect produced by the different tones obtained islimited by the original colour of the fibres forming the flock support,since the laser beam can only darken the colours by melting the fibrespresent in the support with its heat. Therefore, in this case the effectobtained is limited to the different tones that can be obtained from asingle colour, produced by the variation of the heat applied on saidfibres.

There are solutions known in the state of the art to achieve thisdifferentiation effect between the colours of the engraved motif, whichconsist in the use of a two-layer element made up of an outer or upperlayer and an inner or lower layer, such that the colour of the lowerlayer is different to that of the higher layer.

Thus, the application of a laser beam on the outer or upper layer causesthe elimination of part of the material of said upper layer, such thatit reveals the lower layer, producing a two-colour effect that allowsrepresenting a motif with a specific design. An example of thistechnique is found in document U.S. Pat. No. 6,633,019.

In this case it is necessary to use an additional layer with a differentcolour to that of the outer layer of the support, thus achieving thetwo-colour effect.

The object of the invention is therefore to engrave an indicative and/ordecorative motif on an inner flock coating by the action of a laser beamthereupon, producing on said coating at least two areas that can bedifferentiated by the human eye due to characteristics such as colour,photoluminescence, etc., for example, without having to use additionallayers as part of said coating.

DESCRIPTION OF THE INVENTION

In view of the above, the present invention relates to an inner flockcoating for vehicles with an indicative and/or decorative motif whereinsaid motif is located on a visible surface of said inner coating andwherein said coating comprises:

-   -   a support,    -   an adhesive layer located at least over part of the support        layer,    -   a flock layer made up of a number of fibres applied by flocking        technology on at least one part of the adhesive layer,        characterised in that,    -   at least part of the motif is made up of the combination of at        least two visually different areas, a first area made up of part        of the flock layer where it is visible, and a second area made        up of the adhesive layer where it is visible due to the        elimination of part of the flock layer located on top of the        adhesive layer and where the part of the flock layer that has        been eliminated is due to an increase in temperature at said        area, caused by the action of a laser beam projected on that        part of the flock layer,    -   and where the temperature for eliminating the fibres forming the        flock layer is less than the degradation temperature of the        adhesive forming the adhesive layer.

Additionally, the invention relates to the manufacturing process for aninner flock coating for vehicles with an indicative and/or decorativemotif.

A vehicle is understood as any means of transportation for people orobjects such as a car, an aircraft, or a train, for example.

The visible side of the inner coating is the side that is visible to theuser when said inner coating is in its assembly position inside thevehicle.

The definition of the motif as being indicative and/or decorative meansany graphic expression with a purely decorative function or any otherfunction, such as that of indicating a device inside the vehicle, suchas the word “airbag” indicating the location of an airbag, or such as anindicator light on a button activating a mechanism in the vehicle.

The elimination of part of the flock layer is understood as part of thematerial in the fibres forming the flock layer passing from a solidstate to vapour state, either maintaining their original composition ordecomposing into other substances.

In certain special cases said material undergoes combustion whenvaporised, combustion being the destruction of the material by itscombination with O2 when it reaches ignition temperature.

In the particular case of their being combustion, the intensity of thelaser beam is such that when applied on the flock layer it causes thefibres forming said layer to reach their ignition temperature in orderto cause their combustion.

However, the adhesive forming the adhesive layer, as stated above,remains stable within the range of intensities the laser beam is workingin and is therefore capable of maintaining its integrity despite theincrease in temperature caused by said laser beam.

Therefore, and as stated above, in all cases the temperature used toeliminate the fibres forming the flock layer is less than degradationtemperature of the adhesive forming the adhesive layer.

When using the configuration of the invention it is possible to achievean engraved motif on the flock coating made up of the combination of atleast two visibly different areas, on the one hand the area of the flocklayer and on the other hand the area of the adhesive layer. This visualdifferentiation can be achieved, for example, by using adhesives with adifferent colour than that of the flock layer, or by using adhesives oroptionally by the use of fibres with photoluminescent properties, forexample. In either case, the differentiation between each area making upthe motif is visible to the human eye.

Additionally, as a result of the elimination of material from the flocklayer, there is a change in texture that also allows differentiatingeach of these areas by touch.

On the other hand, this visual effect is achieved without having to useadditional layers with respect to those forming the flock coatingitself, since the adhesive layer is an integral part of this coating,being the element the main function of which is to join together theflock layer and the support.

Additionally, and since the adhesive layer is not eliminated with theheating action of the laser beam, this adhesive causes a barrier effectthat protects the materials forming the support underneath said adhesivelayer, such as a fabric support or a plastic support.

Therefore, in contrast to what occurs in other conventional flockcoatings, the adhesive layer making up the flock coating has a triplefunction, to fix the fibres that make up the flock layer to the support,to obtain a two-colour effect by the combination of at least two areas,that made up of the adhesive and that made up of the fibres forming theflock layer, and protection against the laser beam for the layersforming the support underneath the adhesive layer.

The configuration details corresponding to dependent claims 2 to 16 arealso considered included by reference in this description.

DETAILED DESCRIPTION OF THE INVENTION

In view of the above, the present invention relates to an inner flockcoating (1) for vehicles with an indicative and/or decorative motif(10), of the ones made up of a support (2), an adhesive layer (3) and aflock layer (4) that is adhered to the support (2) via the adhesivelayer (3), wherein said motif (10) is located on a visible surface (1.1)of said inner coating (1) and wherein said motif (10) is made up of thecombination of at least two areas of the coating (1), a first area (6)and a second area (5), wherein the first area (6) is made up of at leastone part of the flock layer (4) where it is visible, and where thesecond area (5) is made up of part of the adhesive layer (3) where it isvisible due to the elimination of part of the flock layer (4) thatcovers it, and wherein the part of the flock layer (4) that waseliminated was eliminated by an increase in the temperature of saidpart, caused by the action of a laser beam (9.1). The effect achieved bythe combination of at least two types of areas (5 and 6) to draw themotif (10) is a visual effect, that is, the user is capable ofdifferentiating one area from the other and thus of recognising themotif/(10) by means of the visual differentiation of the different typesof areas.

Therefore, said first and second area (5 and 6) are visually different,due to the different colours of each area, thus obtaining a two-colouredeffect, or due to other properties such as different textures ordifferent tones, for example.

A variation of the invention consists in the use of additives to achieveadditional properties, either in the fibres of the flock layer or in theadhesive, with properties such as photoluminescence, fluorescence or anelectrochromic effect, for example.

In the specific case of photoluminescence in any of the two areas (5 and6), the visual differentiation of each of said areas (5 and 6) occurswhen the coating is subjected to light radiation, such that one of theareas is capable of emitting light, such that the user can see the motif(10) under specific lighting conditions.

FIG. 1 shows an example of the inner coating (1) of the invention madeup of a support (2), which in this particular case has a two-dimensionalconfiguration, two-dimensional being understood as a sheet with twodominant dimensions, width and length; an adhesive layer (3); and aflock layer (4) made up of a set of fibres adhered to the adhesive layer(3) such that they become integral with the support (2) once bound toit.

The support (2) can be made up of materials of different nature, such asplastic components or fabrics, for example. On the other hand, thissupport may have a two-dimensional configuration, such as a sheetelement, for example, or they can have a three-dimensional shape ifformed in three dimensions, for example. Examples are shown below of thedifferent types of support according to their physical configuration.

The adhesive layer (3), in a particular case, is made up of an acrylicresin that is applied on the support (2) in a liquid state and ispolymerised by applying heat once the fibres have been distributed onthe adhesive layer (3).

On the other hand, this adhesive has additives that allow it todifferentiate itself from the fibres forming the flock layer (4). Theseadditives can be pigments providing their colour, photoluminescentsubstances, etc.

Additionally, the adhesive has other additives are allowed to meet thespecifications established for visible parts. The elimination of thematerial forming the flock layer (4) can be carried out by sublimation,decomposition, combustion, etc, as explained above. All of these casescause an elimination of material that reveals the adhesive layer (3),making it visible.

This elimination of material, especially in the flock layer (4), occurat temperatures high enough to cause the elimination of the part of theflock layer (4) the laser beam (9.1) is aimed at, but low enough as tomaintain the integrity of the material forming the adhesive layer (3).

More specifically, the range of temperatures that would causedegradation of the adhesive, for the specific case of acrylic resins,would be above 450° C. Therefore, this temperature should not beexceeded at any time in order to maintain the integrity of the adhesivelayer (3).

The flock layer (4) is made up of fibres of oil derivatives, such asthermoplastic plastics, and especially polyamide (PA66), polyester(PET), polypropylene (PP), etc., or derivatives of natural substancessuch as polylactic acid (PLA), polyhydroxyalcanoates (PHAs) orpolyhydroxybutirates (PHBs).

The geometric features of the fibres are variable depending on both thevisual effect and the feel to be achieved on the coating. The length ofthe fibres ranges between 0.1 and 20 mm and preferably between 0.8 and 7mm, and the density ranges between 0.3 and 15 dtex, preferably between 1and 5 dtex.

The range of temperatures for the elimination of the material in theflock layer (4) ranges between 150° C. and 600° C., preferably between350° C. and 450° C.

The binding of the fibres forming the flock layer (4) on the support (2)is caused by the partial soaking of one end of such fibres into theadhesive layer (3) located on the support (2).

Having applied the flock layer (4) on the adhesive layer (3) and havingcompleted the drying and cleaning operations, an embossment treatmentcan be performed on said coating (1) consisting in hot stamping apattern on said coating in order to achieve different effects on thefibres forming the flock layer.

In order to obtain the motif (10) on the coating, as can be observed inFIG. 1, which shows two different types of areas on the visible side(1.1) of the inner coating (1), these two visually different types ofareas are combined, a first area (6) where the flock layer (4) isvisible and a second area (5) where the flock layer (4) has beenremoved, revealing the adhesive layer (3).

By the combination of these two different types of area, a first area(6) and a second area (5), we obtain the motif (10) on the inner coating(1), in this case, as can be seen in FIG. 2, which shows a perspectiveview of the inner coating (1), the motif (10) in this case beingdecorative.

In other cases, this motif (10) can have an indicative function as inthe case of the word “airbag” indicating the position of this safetyelement in the vehicle, or as a photoluminescent indicator for aspecific device or simply as a reference position in the vehicle.

The first area (6) making up the motif (10) is made up of at least onepart of the flock layer (4), this first area (6) being visible from thevisible side (1.1) of the inner coating (1).

Since the adhesive layer (3) is immediately below the flock layer (4),it is possible that part of the adhesive layer (3) may occasionallybecome noticeable, depending on the density of the flock layer (4),however, in this first area (6) the most visible layer of the coating(1) is the flock layer (4).

The second area (5) making up the motif (10) is made up of part of theadhesive layer (3) where it is visible, due to the elimination of partof the flock layer (4) located on the adhesive layer (3), and where theelimination of that part of the flock layer (4) occurs by an increase intemperature of said part, caused by the action of a laser beam (9.1) onthe flock layer (4).

This laser beam (9.1) is applied by means that generate and direct (9)said beam (9.1) such that it causes the elimination of at least part ofsaid flock layer (4), making the adhesive layer (3) below said part offlock layer (4) visible.

In some cases, the elimination of the fibres of a certain area may notbe complete and there may therefore be some remainder of molten materialthat solidifies in the area the laser beam (9.1) operates in, however,this part is considered negligible with respect to the part of thefibres of the flock layer (4) that has been eliminated.

FIG. 3 shows a variation of the invention. In this case it contemplatesthe possibility of the creation of the motif (10) by the combination ofother possible types of areas with the first area (6) and the secondarea (5) described.

Specifically, in an example represented in FIG. 3, showing fourdifferent types of areas, a first area (6), a second area (5), a thirdarea (7) and a fourth area (8). The first and second areas (5 and 6)have already been described above, and are therefore considered defined.

The third area (7) is made up of the material resulting from havingheated the fibres of the flock layer (4) until they melt, but withouteliminating them, leaving the adhesive layer at least partially coveredby said molten material, caused by an increase in temperature in thefibres by the action of a laser beam (9.1).

Therefore, different effects can be achieved on the flock layer (4) bycontrolling the intensity of the laser beam (9.1). In this case, wherethe material forming the layers is melted, the heat received by saidfibres, generated by the laser beam (9.1) is less than the heat receivedby the fibres forming the second area (5) forming the motif (10), wheresaid fibres are eliminated.

The fourth area (8) making up the motif (10), shown in FIG. 3, is formedon the one hand by part of the support (2) on which neither a flocklayer (4) or an adhesive layer (3) have been applied. Therefore, theappearance offered by this support (2) contributes, by its combinationwith the remaining areas forming the motif (10), to establish the finalappearance of said motif (10).

FIGS. 4, 5 and 6 show examples of the different configurations thesupport (2) may adopt.

First of all, FIG. 4 shows a support (2) with a configuration having twodominant dimensions, i.e. a two-dimensional configuration in which saidmeans are shaped by a sheet, e.g. of fabric, paper or plastic, i.e. inorder to obtain the coating (1), the application of both the adhesivelayer (3) and the flock layer (4), as well as the drawing of the motif(10) is carried out on a two-dimensional element.

In this case, in a subsequent stage, the coating (1) obtained can beshaped in order to obtain a coating part for inside a vehicle with athree-dimensional configuration, either by means of its application on apart that has already been shaped, or by its individual shaping ortogether with the material that will make up the part.

FIG. 5 shows the configuration of a support (2) with a three-dimensionalconfiguration. In this case, both the application of the flock layer (4)and of the adhesive layer (3), as well as the drawing of the motif (10)is carried out on a three-dimensional support.

FIG. 6 shows a third example of the support (2), where said means have atwo-dimensional configuration, such as the one shown in the Figure, or athree-dimensional configuration (not shown), and where said support (2)is formed in turn by a second support (20), an adhesive layer (30) and aflock layer (40), joined and superimposed consecutively.

Therefore, in order to make the coating (1), an adhesive layer (3) isapplied on the flock layer (40) and then another flock layer (4) isapplied such that adhesive layer (3) acts as a connection of the flocklayer (4) with the support (2).

Finally, the stages of the manufacturing procedure for the coating ofthe invention are described, which are represented as a diagram in FIG.7.

First of all, and in order to produce the coating shown in step a) ofthe process, a support (2) is needed on which to apply an adhesive layer(3). This adhesive layer (3) is applied upon at least one part of thesupport (2).

A flock layer (4) is applied below, corresponding with at least part ofthe adhesive layer (3), and preferably over the entire surface formingsaid adhesive layer (3).

The application of said flock layer (4) can be carried out, for example,by means of an electrostatic flocking process consisting in theprojection of the fibres making up the flock layer (4) through anelectrostatic field that orients them, onto an adhesive layer (3)located on a support (2), such that said fibres are perpendicularlyarranged with respect to the support.

With this procedure, one of the ends making up said fibres is embeddedin the adhesive layer to thus fix its position on the support (2).

The motif is then created, as can be seen in steps b), c) and d) of theprocess represented in FIG. 7, by the combination of two different areasof the coating (1), a first area (6) and a second area (5).

The first area (6) is formed in turn by part of the flock layer (4).

The second area (5) is made up of part of the adhesive layer (3) whereit is visible, due to the elimination of a part of the flock layer (4)located on the adhesive layer (3), and where said elimination of saidpart of the flock layer (4) is produced by an increase in temperature insaid part, caused by the action of a laser beam (9.1) on the flock layer(4), shown in step c) of the procedure, applied by laser beam (9.1)generation and direction means (9), such that it causes the eliminationof at least part of said flock layer (4), making the adhesive layer (3)under said part of the flock layer (4) visible.

As described above, the support can have a two-dimensional or athree-dimensional configuration, as shown in FIGS. 4 and 5. On the otherhand, the support may be made up of a single layer or by athree-dimensional part, or by a multilayer element such as the one shownin FIG. 6, such as a flocked element.

On the other hand, the motif (10) obtained can be seen by the user, whocan differentiate the different shapes making up the motif, either bythe different colours of the different areas or by the photoluminescentproperties of some of the flock layers (4) or the adhesive layers (3)making up the coating (1), or any visible difference in the trimming.

On the other hand, the motif (10) can be formed by the combination ofother areas with the first and the second area (5 and 6) describedabove. Such as a third area (7) where the material forming the fibres ofthe flock layer (4) are made to melt, causing a change of tone in thefibres that varies according to the intensity of the laser beam (9.1),or a fourth area made up of part of the support (2) itself on whichneither adhesive or fibres have been applied.

Variations in materials, shapes, size and the arrangement of thecomponent elements, described in a non-limiting manner, do not alter theessence of this invention, this being sufficient for its reproduction byan expert.
